There is a difference between the video formats in the US and the UK.
In the US, video runs at 30 frames/sec, while in the UK, video runs
at 25 frames/sec. UFO was filmed on 35mm film (like a movie), which
runs at 24 frames/sec. Because of these different frame rates, when
converting film to video, the resulting video speed is different.
The US video runs very close to the original film speed, while the
UK video runs 4% faster.

And this doesn't just apply to UFO -- it applies to all theatrical
films.
